sean and leah are playing a computer game. sean scored 72,491 points. leah scored 19,326 points more than sean. how many points did leah scored? tape diagram

Answers

Answer:

Leah scored 91,817 points.

Step-by-step explanation:

Sean and Leah are playing a computer game.

Let Leah scores x points.

Sean scored 72,491 points.

Leah scored 19,326 points more than Sean.

So, $x=72491+19326$

= 91817

Hence, Leah scored 91,817 points.

If Sean scored 72,491 points and Leah scored 19,326 more then you add 72,491 and 19,326 to get your answer of 91,817

Explain how to break apart the addends to find the sum 25+16

Answers

(20+5)+(10+6)
you are supposed to use place value to break it down

Final answer:

To find the sum of 25+16 by breaking apart addends, you can break the numbers into tens and ones. Adding the separate tens and ones gives 30 and 11 respectively. Adding these results together, the final sum is 41.

Explanation:

The subject of your question is a fundamental mathematical concept known as addition. Specifically, you have asked to explain how to break apart the addends to find the sum of 25+16.

When we talk about 'breaking apart addends', we're referring to the strategy of making it easier to compute a big addition problem by breaking the numbers into more manageable pieces. You can usually do this by breaking numbers down into tens and ones. This is also known as 'use place value' in numerical operations.

Let's break the operation down: 25 + 16.

First, identify the tens and ones in each addend - 25 is made up of 2 tens (20) and 5 ones, and 16 is made up of 1 ten (10) and 6 ones.
Second, add together the tens, then add together the ones. You get 2 tens (from 25) + 1 ten (from 16) = 30, then add 5 ones (from 25) + 6 ones (from 16) = 11.
Lastly, add these two results together. You get 30 (the sum of tens) + 11 (the sum of ones) = 41. So, the sum of 25 and 16 is 41.

Breaking apart addends helps make mental computation of these large numbers easier.
